When you describe a process you go step by step explaining what you do or how the process takes place. For this kind of writing you will need time markers as: first, second, third, then, later, after, before, etc. You also might use verbs in infinitive form to explain what process you are going through or you are seeing.
Follow these steps:
1. Read the instructions, cut them and paste them to your wiki. Underline the words that are time markers.
An Arithmetic Magic Trick
Think of a 2-digit integer. Subtract from the number the sum of its digits and find the result in the table below. Note that each cell of the table contains a number and a geometric shape. Concentrate hard on the shape that shares a cell with the result of your calculations. When ready, press the "Check it!" button ...
2. Play and try to explain why the magic trick worked.
ItIs really surprising. I think that existthere aresome mathematical methodS to solve this, because it is really completed for all the numbers of the square. The solution will always give the number 0 or some number multiple of 9 with the same figure!!!
3. Check the explanation below the trick. Was it the one you were thinking of? Explain.
The explanation is related a little with what I thought that it happened, but particularly I didn't have idea thataboutwhy I gavegotmultiples of nine
Answer:
This is because when you have a whole number and this is the absolute value remains the same, the result will always be a multiple of 9. The figures of the multiples of 9 will always be the same.
